This invention pertains to a sterilizing device especially adapted for sterilizing the tubes of vacuum milking machines andthe primary object of this invention is toppro- 6 vide a device for sterilizing the milking tubes in a simple, inexpensive and practical manner;

A still further object of the invention is to provide a sterilizer for the purpose above l mentioned whichV is portable, being easily moved from place to place so that the sterilizing of the tubes may be accomplished either indoors or out of doors. v

A still further object of the invention is to provide a device of the character above mentioned, whereby the milking tube after each milking operation may be subjected to a sterilizing treatment of lye solution until such time as the milking machine is to be again "i put into use.

A still further object of the invention is to provide a sterilizing device of the character above mentioned Which includes a suitable cabinet for accommodating the milking "-ff tubes during the period of sterilization.

Other objects and advantages of the invention will become apparent from a study of the following description, taken in connection With the accompanying drawings Where- 1n:

Figure 1 is an end elevational view of the device.

Figure 2 is a vertical longitudinal sectional elevational view therethrough.

7'7 Y Figure 3 is a horizontal longitudinal sectional vievv taken substantially on the line 3-3 of Figure 2.

Figure 4 is a detail sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a sectional elevational view taken substantially on the line 5-5 of Figure 4.

Feferring more in detail to the drawings, it will be seen that the sterilizing device com- 4 prises a cabinet 5 Which is of any suitable size and may be constructed from metal,

Wood or any other suitablermaterial. One side oi the cabinet 5 is opened, and hinged doors 6 are provided for the open side of the 459 cabinet.

Suitably mounted in the cabinet 5is a tray or Vrack 7 provided with a `plurality, of elongated slots 8 enlarged atone end for initially receiving a teat cup..

j Supportedl on the rear VWall of the cabinet beneath therack or tray 7 are brackets 9 which support for vertical adjustment a horizon-tallydisposed feed pipe l0 Which at one end extends through a vertical slot 11 provided-in an end Vvvallof the cabinet 5. VOn said one end, there is mounted on the pipe a cupV 12 of suitable capacity and designed to receive the neck of an inverted'jar or con-k tainer 13. J ar 13 is supported in a vertical position through the medium of a suitable bracket 14.

A solution of lye or likek sterilizingl solu-4 tion is contained in the jar 13 and When the I jar 13 is positioned with respect tothe cup l2 as suggested inFigures 1 and '2, the solution from the jar will, be fed by gravity to the 'cup 12 and from the cup 12 vvill pass through the pipe 10. 1

For securing the pipe 10 at the desired vertical adjustment, there is provided on ythe end wall of the cabinet adjacent the slot 1,1 a sup-` porting plate `15 that may be secured at the ,desired adjustment by suitable slot" and bolt means 16. The plate 15 at its upper edge is provided Withv an arcuate notch for accommodating an adjacent portion of the pipe 10. Obviously by securing the plate 15 in a raised or loweredposition pipelO vvill befretained at the desired adjustment and cup 12 adjusted vvertically relative to the jar 13 for controlling the lovv from the jar 13 tothe cup 12in a manner thought apparent.

l/Vithin the cabinet 5, the pipe 10 is provided vvith ka plurality of relatively spaced pet cocks 17 each of whichv is adapted to accommodate the free end of a milk tube'lSl provided with the usual teat cup 19 that may be engaged Witha desired one of the slots `Stor suspending the teat cup within the cabinet. In operation, and as is apparent lfrom` a study fof Figure 2, subsequentv to a milking operation, the milktubes of al vacuum milkingmachine may be arranged in the cabinet -fas shoWnin Figure 2 With the ends of the tibes 18 suitably connected to the pet cocks 1 Y ll of the pet cocks 17, or selected ones of the pet cocks maybe opened, and as is apparent, the solution from the jars 13 emptying into the cup 12 will flow by gravity from the cup through the pipe 10 and through the several pet cocks to pass into the tubes 18 and the cups 19 associated with the tubes to the capacityof the tubes and theircupsr.Y

When the milk tubes are to be used, the same may be disengaged from the pet cocks 117,;

andsubsequently connected to the vacuum system yof the milkingmachinefor rinsing the milking tubes, a practice vcommon to the dairyman'; Thus, with a device of this character, the milking tubes may be first treated Y to a solution of lye or other sterilizing solution, and then just prior to use may be rinsed and when coupled to the machine for milking, will be in a thoroughly sanitary condition. f

Leaving the lye solution in the milk tube l i until just before these tubes are to be coupled with the milking tubes for milking pur'-v oses, will convert any residue of milk and fat left in the tubes subsequent to milking,

i into soluble soaps 'and ash that can easily be-rinsedV out withY cold water.

the open ends of the cups uppermost, a rela tively fixed container, a relatively rigid hori- Zontally disposed conduit adjustable vertically with respect to said means and said container, said conduitbeingprovided with a rcup for rreceiving the contents of said container,'and'being also provided with valved means adapted YVto be connected to the milk tubesl whereby the contents of said container is` fed to the teat cups, under control.
